I am a professional travel photographer with a problem. You see, I still use film for my work and I recently lost my x-ray protection bag, which I used when passing through airport security to protect my film (I often use high-ISO rolls). I've had no luck finding any stores that sell them over here (in the Netherlands) but I'll be passing over to London for the New Year period.
So, would any of you know where I could find the x-ray bag I need?
